      Burg, Ludovic; Lino, Christophe; Christie, Marc (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Efficient visibility computation is a prominent requirement when designing automated camera control techniques for dynamic 3D environments; computer games, interactive storytelling or 3D media applications all need to track ...
    • Binary Ostensibly-Implicit Trees for Fast Collision Detection

      We present a simple, efficient and low-memory technique, targeting fast construction of bounding volume hierarchies (BVH) for broad-phase collision detection. To achieve this, we devise a novel representation of BVH trees ...
    • Motion Retargetting based on Dilated Convolutions and Skeleton-specific Loss Functions 

      Kim, SangBin; Park, Inbum; Kwon, Seongsu; Han, JungHyun (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Motion retargetting refers to the process of adapting the motion of a source character to a target. This paper presents a motion retargetting model based on temporal dilated convolutions. In an unsupervised manner, the ...
    • Style-Controllable Speech-Driven Gesture Synthesis Using Normalising Flows 

      Alexanderson, Simon; Henter, Gustav Eje; Kucherenko, Taras; Beskow, Jonas (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Automatic synthesis of realistic gestures promises to transform the fields of animation, avatars and communicative agents. In off-line applications, novel tools can alter the role of an animator to that of a director, who ...
    • Accurate Real-time 3D Gaze Tracking Using a Lightweight Eyeball Calibration 

      Wen, Quan; Bradley, Derek; Beeler, Thabo; Park, Seonwook; Hilliges, Otmar; Yong, Jun-Hai; Xu, Feng (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      3D gaze tracking from a single RGB camera is very challenging due to the lack of information in determining the accurate gaze target from a monocular RGB sequence. The eyes tend to occupy only a small portion of the video, ...
    • Single Sensor Compressive Light Field Video Camera 

      Hajisharif, Saghi; Miandji, Ehsan; Guillemot, Christine; Unger, Jonas (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      This paper presents a novel compressed sensing (CS) algorithm and camera design for light field video capture using a single sensor consumer camera module. Unlike microlens light field cameras which sacrifice spatial ...
    • RGB2AO: Ambient Occlusion Generation from RGB Images 

      Inoue, Naoto; Ito, Daichi; Hold-Geoffroy, Yannick; Mai, Long; Price, Brian; Yamasaki, Toshihiko (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We present RGB2AO, a novel task to generate ambient occlusion (AO) from a single RGB image instead of screen space buffers such as depth and normal. RGB2AO produces a new image filter that creates a non-directional shading ...
    • Prefilters for Sharp Image Display 

      Rocha, Luís Cláudio Gouveia; Oliveira, Manuel M.; Gastal, Eduardo S. L. (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      In this paper we use a simplified model of the human visual system to explain why humans tend do prefer ''sharpened'' digital images. From this model we then derive a family of image prefilters specifically adapted to ...
